Doug, I just wanted to drop you a short note – I’m so pleased with the new solar heat system for the pool. With *no extra pump running* I’m getting a pool that has been toasty warm since we installed the new panels. My wife likes the pool at 88 degrees (warm, I know) and we’ve used zero natural gas to keep it there. I really appreciate you and your guys working with me to install the system – I feel like I got an education as well as a big break on my electric bill. The old “booster pump” we took out (for the old system) ran for hours at 1000 Watts – I’m glad to rid of that! And, I know it’s a little thing, but the flow-meter you installed showing me how many gallons-per-minute the pump is moving allows me to better understand the whole system. I can’t say enough about the good work you and your team did – I feel like I got a solution that perfectly matched my situation – thanks again.
